Definitions

  • connection formed by a flexible tube was designed between the reservoir containing the fluid reserve and the applicator, thus facilitating manual operations.
  • the aim of this invention is to provide an improvement to fluid dispensers, in particular for gluing parts, comprising a glue reservoir, an applicator connected to the reservoir by a flexible tube and a pneumatic pulse generator for creating momentary excess pressure on the free level of fluid in the reservoir thus ejecting doses of fluid through the applicator.
  • the dispenser of the invention is characterized in that the dispenser comprises, on a support, a receptacle for the applicator, means for holding the reservoir and a stabilizing arrangement, the latter ensuring that the free level remains at an approximately constant level with respect to the applicator placed in its receptacle during the functioning of the dispenser.
  • FIGS. 1a-1c are diagrammatic views showing the principle of this embodiment at different stages of dispensing
  • FIG. 2 is an elevation of the embodiment described
  • FIG. 3 is a top plan view of the dispenser of FIG. 2.
  • FIG. 1 illustrates the principle of the device, i.e. a reservoir 1, of which the level of the contents may vary during the use of the device between three stages designated by A, B and C in FIG. 1.
  • This reservoir is suspended by a spring, the characteristics of which it is not necessary to specify for the moment, and which is designated by 2, from a fixed support 3.
  • a flexible tube 4 penetrates inside the reservoir 1, the lower end of the tube being located close to the bottom of the reservoir 1 and is therefore immersed in the liquid contained in this reservoir.
  • This flexible tube 4 ends at an applicator 5 which is attached to a receptacle 6 integral with the support.
  • the applicator comprises a vertically disposed needle 7, the tip of which is at a slightly lower level than the level 8 of the liquid in the reservoir 1.
  • FIGS. 1 and 2 the applicator is shown in the rest position. Periodically, an operator takes it to carry out a gluing operation and then replaces it in the position shown.
  • the letters A, B and C designate three different levels of the contents of reservoir 1. As the reservoir empties, its weight lessens, so that the spring 2 contracts. The displacement of the reservoir by the spring is regulated so that the level 8 of the liquid remains constantly at the same height. Thus, when the applicator is in its rest position, i.e. fixed to the element 6, the quantity of liquid it contains and which the tube 4 contains, is constantly the same, which ensures that the applicator is always ready for the next fluid dispensing operation.
  • FIG. 1 shows the action of a pneumatic pulse generator in the form of a pipe 9 opening into an upper area of the reservoir 1, practically in contact with the liquid.
  • a pneumatic pulse generator in the form of a pipe 9 opening into an upper area of the reservoir 1, practically in contact with the liquid.
  • This illustration is intended here solely to demonstrate the way in which the system functions. It will be understood that a pulse generator causing momentary excess pressure in the upper cavity of the reservoir will force a precalibrated dose of liquid to pass into the flexible tube 4 and, therefore, a drop will be emitted at the tip of the needle 7.
  • the pneumatic pulse generator may function according to a different but equivalent system and may have, for example, an arrangement avoiding all direct contact between the air and the liquid contained in the reservoir.
  • FIGS. 2 and 3 show an actual embodiment of the device.
  • the support 3 comprises a base plate 10, a rigid upright 11 fixed vertically to the base plate 10, a sheet metal reinforcement wall 12 and a vertical rod 13 on which is fixed a vertically adjustable bracket 14 intended to receive the applicator 5.
  • the attachment element 6 is constituted here by an opening in the bracket 14 adapted to receive the body of the syringe 5, the needle 7 of which is disposed vertically downwards.
  • FIGS. 2 and 3 also show the reservoir 1, the detailed structure of which it is not necessary to describe completely at this point.
  • a connection piece 15 is disposed on the cover of this reservoir for the passage of the flexible tube 4 which connects the reservoir to the applicator 5.
  • Another opening 16, also disposed in the cover of the reservoir allows pneumatic pulses to be communicated to the reservoir 1 through another flexible tube designated at 17 in FIG. 2.
  • the flexible tube 17 emanates from a connection piece 18 which is integral with the base plate 10 and which passes through a drier 19 and communicates itself, via a connection piece 20, with a feed pipe 21 which directs the pneumatic pulses generated by an electronically controlled device which is known per se and which does not therefore constitute part of this invention.
  • the reservoir 1 is suspended by means of two diametrically opposed pegs 22 with two parallel arms 23 of a frame 24 comprising a crosspiece at its rear end and bearing two pivot pins 26 which fit into axial bearings 27 contrived horizontally in the upright 11, in the vicinity of its upper end.
  • the frame 24 is articulated on the upright 11 and supports the entire reservoir 1 by its two parallel arms 23, 23.
  • the action of two springs 28 and 29 bent between different locations of the frame and the base 10 or the upright 11, is coordinated to compensate the position of the frame 24 as a function of the degree to which the reservoir is filled 1.
  • Spring 28 is constituted by a thread of curved steel whilst spring 29 is a spiral spring fixed on the one hand to the base of the upright 11, and on the other hand, to an eccentric 30 which is fixed by a screw and a spring 31 to one of the arms 23 of the frame 24 at the back of the upright 11.
  • the eccentric 30 allows easy regulation of the force of the spring 29 and therefore allows the height of the reservoir 1 to be adjusted as its contents increase or decrease.
  • the frame 24 comprises in addition a transverse rod 32 extending between the two arms 23 in the vicinity of the location of the reservoir 1.
  • a vertical rod 33 which enters into a blocking cylinder 34 is fixed to this transverse rod 32.
  • This blocking cylinder which may be of the electromagnetic or pneumatic type, for example, may be actuated as required and, when it is actuated, blocks the rod 33.
  • the frame is thus rigidly fixed with respect to the support 10, 11 and there is therefore no risk, for example if the device should move, of causing inopportune oscillation of the reservoir 1.
  • This blocking means is particularly useful when the dispenser described is incorporated with automatic apparatus, for example an apparatus for assembling and gluing parts.
  • automatic apparatus for example an apparatus for assembling and gluing parts.
  • the fluid dispenser is placed in the vicinity of the parts at the moment of the fluid dispensing operation and that it may be moved aside during the intervals between these operations.
  • the apparatus described may easily be mounted on a vertical slide, a mobile table or a robot.
  • a position sensor 35 On the upright 11.
  • the frame assumes the limit position when the reservoir is practically empty.
  • the sensor 35 may therefore be placed so as to detect the moment when the frame reaches this limit position so that it will signal, for example, the need to refill the reservoir.
  • the detector may also transmit a command to increase the duration of the pneumatic pulses when the reservoir approaches the completely empty state.
  • the stabilizing arrangement described above could comprise a sensor to detect the height of the free level with respect to the reservoir and control means subordinate to the information from the sensor, functioning so as to supply the reservoir from time to time from a fluid reserve container.
  • the control means subordinate to the information from the sensor could comprise, for example, a pump causing fluid to pass from the container to the reservoir, or a clamp comprising a flexible tube which connects the container to the reservoir.
  • the device described is suitable for cyano-acrylate type glues, and for dispensing volatile or aggressive liquids.
  • a further feature of the dispenser is that the volumes of air introduced into the reservoir always cause the same excess pressure effect, which was not the case with former apparatuses in which the level of liquid varied as the reservoir emptied.
